Hello,

Anyone know how the least_conn upstream option works in nginx plus?

http://nginx.org/en/docs/http/ngx_http_upstream_module.html#least_conn
says
"Specifies that a group should use a load balancing method where a request is passed to the server with the least average response time and least number of active connections, taking into account weights of servers"

How does nginx plus use the three variable to determine which server to use?
Is the "total" weight dynamically determined as: weight * 1/response time * active connections or some other formula?

Thanks.
